Temporal refraction and reflection in modulated mechanical metabeams:
theory and physical observation
Temporal refraction and reflection in modulated mechanical metabeams:
theory and physical observation
Wave reflection and refraction at a time interface follow different conservation laws compared to conventional scattering at a spatial interface. This study presents the experimental demonstration of refraction and reflection of flexural waves across a temporal boundary in a continuum based mechanical metabeam, and unveils opportunities that emerge by tailoring …
